This will be my third try now

Hey guys,

I really need to figure this out. I've been at it for the longest time. My best, and last try a few months ago I had went for a month and a half (almost). My weakness and triggers were that I was on a lot of Discord servers (voice chat, text chat program for those of you who don't know) that had pornographic #nsfw materials. I also had been triggered by a girl who wanted to masturbate with me on voice chat. I fell for it and caved in and lost my progress. At the time, another weakness was that I was so happy about the almost two months. Something in your brain changes when you reward yourself, you act as if the battle is already won and let your guard down. Another trigger is that I have way to much fucking pornography on my PC from hentai to bookmarks of pornhub videos. This goes back to when I was like 14 years old and now I'm in my early 20s. I have still never held hands with a girl. I legitimately feel like I was doing great before I fell off the wagon. I had started exercising, losing weight, and more. This issue is legitimately effecting every part of my life. I have no understanding of women and some part of me thinks that I can make myself look so bad and basically get someone to pity fuck me. I don't get why I would want this... But I definitely act it. When talking to new women, online mostly... Because I'm not sure what to do when I go outside.

Lots of people say:
Go to a bar
Go to a club
Drink Booze

Are these really... helpful? I don't have a problem talking with women, my issue is the fact that I'm a little fucking closet pervert. AND I HATE MYSELF FOR NOT BEING ABLE TO HAVE A LITTLE BIT OF SELF CONTROL. It's honestly terrible, a man is supposed to be able to think with his mind and not with his dick, yet I cannot do this. I feel like a child still, yet I have a good job and stuff. I still live with my parents.

After I fell off the wagon last time, I had tried for almost two months to get back on it. It's been a while now and I feel ready to try again. What should I do first? I think it's important to know what triggers me, and I do now. So, do I leave all the discord servers which have triggering content? Do I delete my porn stashes? What do you guys think? I'm tired of being so lonely, I want to make changes, but I don't want to fail again.
